Danielle was living in a new city with no local bank of her own. She desperately needed to find a bank to cash her paycheck. For more than two weeks, she made attempts one after another but in vain. How could she continue to support herself and her two children as a single mother?
Taking a break from her struggles, Danielle decided to attend a meeting at the local women's resource center. The women there had been a strong source of encouragement since she fled her home in fear for her safety. Sitting next to Danielle, Amy began to share the details of her desperate situation. She was just days away from losing her home and her car. Her phone and electric services were both scheduled to be canceled. She had nothing left.
As Amy described the degree of the situation, Danielle heard God’s soft whisper in her heart: "After the meeting, give Amy twenty dollars." Danielle immediately thought, “But I can't. I only have forty dollars. She heard the __voice__ again. Danielle knew she needed to follow . When the meeting ended, she reached into her purse and quietly handed twenty dollars to Amy. Knowing Danielle's situation, Amy was unwilling to accept it at first. But as a crowd of women approached to give Amy hugs of support, Danielle told her that God wanted her to have it. Then Danielle left.
Now with just twenty dollars left in her wallet, Danielle decided to try cashing her paycheck at just one more bank before heading home. While she expected the rejection she had received at so many other banks, she was somehow filled with renewed confidence and optimism. Hopefully, she walked into the bank next to the women's center. Moments later, the bank cashed her paycheck with no questions asked. Wearing a big smile, Danielle returned home.
It has been three years since that day. Realizing true hope has no price, she continues to be thankful for the lifetime supply that she received for just twenty dollars.

I don't know what the underlined sentence has to do with the theme of the passage, especially the "price". From what context can we know true hope has no price?
